Description
Technical field
the present invention relates to core making machine field, particularly relate to a kind of upper core box lazy-tongs of core making machine.
Background technology
upper core box hoisting mechanism is the important component part of core making machine, in shooting case of core maker sand and air blowing coremaking process, upper core box need with lower core box press seal, on most of type, core box and lower core box are due to the demand of device action, need upper and lower synchronization lifting; After core has solidified, core by after plunger tip effect ejects upper core box on equipment, need complete and got core.
core box hoisting mechanism on existing most of core making machine, mainly comprise left and right/former and later two hydraulic cylinders/air cylinder driven mechanism, four sides are guide post and fairlead, core box connecting plate on the bottom be connected with guide rod, the synchronous frame in top connected with driving mechanism and guide post.Fairlead and driving mechanism and core making machine upper spider are fixed, and guide post, upper core box connecting plate and synchronous frame oscilaltion realize upper core box lifting action.Wherein: 1, control mode: owing to adopting two independently driving mechanisms, action cannot Complete Synchronization; 2, process, the trueness error of assembling: four side guide posts and the fairlead resistance that leads is inconsistent; 3, core manufacturing craft demand: core is not arranged between two parties, or core profile size deviation, cause core box side to lay particular stress on.Above 3 main causes easily cause four side guide posts to go up and down with different paces and cause, the asynchronous problem of core box in generation.
the synchronous frame in the main top portion of existing structure overcomes above problem.The synchronous frame in top and guide post generally adopt guide post end screw to fix, or adopt guide post flange screw fixed form.The synchronous frame independent suspension in top, is not connected with other parts, this similar cantilever design.In actual use, although certain synchronous effect can be had, the asynchronous problem of synchronous frame itself cannot be overcome, cause core box to be elevated asynchronous.The asynchronous of synchronous frame itself also can be caused and guide post Joint failure, and synchronous frame synchronous effect was lost efficacy, and upper core box lifting is asynchronous more serious.About upper core box lifting or both sides, front and back are asynchronous, and upper and lower core box parting when easily causing core making machine to run, makes made core produce overlap, produces useless core.In addition, easily cause plunger tip effect unbalanced, core cannot be ejected upper core box or by bad for core top.
